#
# raidtools-1.00 uses _llseek via syscall5() which is not x86-pic 
# compatible We can compile all of raidtools with -fno-pie and every 
# binary will be an ET_EXEC file, or we can -fno-pie the single 
# problematic file raid_io.c and then everything will be built as an 
# ET_DYN file but will contain text relocations.
#
# On hardened glibc systems it may be desirable to have a ET_DYN over 
# ET_EXEC files even if they have text relocations.
#
# On hardened uclibc systems we just disallow text relocations, and this 
# patch wont work.
#
# Either way the check can be downgraded from filter-flags -fPIC to 
# -fPIE for raidtools.
#
# What's needed is good way to work around syscall5() eatting up the ebx 
# register on x86. ideas? options that don't depend on kernel/header
# changes?
#
# The prototype looks like this in raid_io.c
#  static int _llseek (unsigned int, unsigned long,
#                  unsigned long, long long *, unsigned int);
#
#  static _syscall5( int, _llseek, unsigned int, fd, unsigned long, offset_high,
#                 unsigned long, offset_low, long long *, result,
#                 unsigned int, origin)
